Gaga performed with THE ROLLING STONES. She should probably just retire now.

We don't have to tell you that Lady Gaga's had a lot of cool things happen to her (um, hello, THE FLOWER HELMET), but performing with THE ROLLING STONES? The Lady should just up and retire right this minute, because it probably doesn't get any better than that. Lady Gaga joined the legendary troupe at their "One More Shot" pay-per-view event event this past Saturday, and not only did she fearlessly rock a striped onesie (which honestly would have been enough for us to be wildly impressed), but she also slayed her verse of the Stones' classic "Gimme Shelter."

Watch Lady Gaga perform "Gimme Shelter" with The Rolling Stones after the jump.

True to form, Gaga came out prancing (literally prancing and doing a jig vaguely reminiscent of that one time Ashlee Simpson lip-synched on "SNL") as she stormed the stage for the second verse of the song. She totally nailed her vocals (including that famous high note in the track's chorus), and by some miracle of god managed to stay vertical while jogging around in some seriously massive platform heels. As you might expect, Gaga seemed right at home with the veteran rock legends, and there may or may not have been a little dance-off between Mick Jagger and Gaga toward the end of the performance. Which was probably the highlight of Gaga's life and, sadly, ours too!
